OK, I took a look at this. A few disjoint thoughts
- I am seeing a slowdown between 5.8 and 5.10. However, it is very small. With 5.8, I’m getting around 14 timesteps per second, on 5.10 I’m getting about 11 timesteps per second. This is on my Macbook. I then tried Linux, and Linux remote server (software rendered). Only the software rendering seemed to lag somewhat, but was still extremely usable.
- I tested with just play, then drug the Annotate Time time slider. Again, results were extremely similar.
- Your dataset is a weird one. Time is not consistent. I believe this was not the issue, but it is strange.
- My speculation is that you are falling out of hardware rendering into software for some reason.
- Try deleting your configuration files. These tend to “rot”, and if you have been using paraview for years, but haven’t cleared the out, now is a good time. Edit/ Reset to Default Settings.
- As a diagnostic tool, so we can add numbers to “man, this feels slow”, in the settings/ Renderview/ Advanced at the bottom is a “Show Annotation” checkbox.
- As another diagnostic tool, look in Help/ About, and look at the rendering between 5.8.0 and 5.10.0. Are they both hardware?
That’s about all I can think of…
